MEREDITH: [talking about her new roommates] "They're just... everywhere, all the time. Izzie's all perky and George does the thing where he's helpful and considerate. They share food, they say things, they move things, and they breathe. They're, like, happy." CRISTINA: "Kick 'em out." MEREDITH: "I can't kick them out, they just moved in. I asked them to move in." CRISTINA: "Okay, so what, you're just going to repress everything in some deep, dark, twisted place until one day you snap and you kill them?" MEREDITH: "Yep."CRISTINA: "This is why we are friends."
